Summary
Microwave ablation (MWA) and radiofrequency ablation (RFA) are effective and safe treatments for benign thyroid nodules (BTNs). While both methods show comparable short-term efficacy and safety, RFA offers slightly better cosmetic outcomes.
Area of Science:
- Endocrinology
- Minimally Invasive Surgery
- Medical Imaging
Background:
- Benign thyroid nodules (BTNs) are common, and while often asymptomatic, they can cause cosmetic concerns or compressive symptoms.
- Minimally invasive thermal ablation techniques, including microwave ablation (MWA) and radiofrequency ablation (RFA), are increasingly used for BTN treatment.
- Comparative data on the short-term efficacy and safety of MWA versus RFA for BTNs are limited.
Purpose of the Study:
- To prospectively compare the short-term efficacy and safety of microwave ablation (MWA) and radiofrequency ablation (RFA) in treating benign thyroid nodules (BTNs).
- To evaluate differences in volume reduction rates, effective rates, cosmetic scores, and complication rates between MWA and RFA.
- To provide evidence-based insights for selecting the optimal ablation technique for BTNs.
Main Methods:
- A prospective randomized controlled trial involving 36 patients with solid or predominantly solid BTNs.
- Patients were randomized (1:1) into either the MWA group or the RFA group (18 patients each).
- Volume reduction rates (VRRs), effective rates (VRRs≥50%), cosmetic scores, and complication rates were assessed at 1, 3, and 6 months post-treatment using statistical analysis (t-test, chi-squared test).
Main Results:
- Both MWA and RFA significantly reduced nodule volume with comparable short-term efficacy and safety profiles.
- The RFA group demonstrated significantly higher VRRs at 3 months compared to the MWA group (62.08%±12.46% vs. 46.90%±23.16%, P=0.021).
- The RFA group achieved a lower cosmetic score (1.78±0.43) than the MWA group (2.17±0.51, P=0.019), indicating better cosmetic improvement.
Conclusions:
- Both MWA and RFA are effective and safe treatment options for benign thyroid nodules, offering comparable short-term clinical outcomes.
- Radiofrequency ablation may provide slightly superior cosmetic results compared to microwave ablation for benign thyroid nodules.
- Further long-term studies are warranted to fully elucidate the comparative effectiveness and durability of MWA and RFA for BTNs.
